I thought it would be beneficial to put some of these rock star directories through my basic back link qualification process to see if any of the big names actually deliver on their promises. As a caveat I’d like to point that this research was conducted to determine a directories benefit to organic search placement and does not in any way reflect the traffic driving capabilities of such directories. In addition I’d like to point out that I’ve picked the ‘best’ category for my listing, this being the one that most accurately reflects the target sites content (in this case furniture/living room furniture/sofas etc).
